In 2011, a small group of previously unconnected northern Sydney locals had their first UAP sighting experience together in a collective setting. At a loss as to where to turn for information and support, the group opted to take the matter into their own hands, and set up a monthly discussion group for this purpose.

In 2012, this core group became connected with other individuals in the community who had had similar experiences. They began actively reaching out to the wider community with the goal of expanding their knowledge base and understanding of these events, and North Sydney Forum was born. The group is now one of the largest of its kind in the southern hemisphere.

Core members make regular trips to Chile, Peru and Nevada, where they have established important relationships with researchers in the field.
